ROBOTIC TRANSTIBIAL PROSTHESIS WITH DAMPING CONTROL IMPROVES AMPUTEE'S LEVEL-GROUND WALKING AT DIFFERENT SPEEDS

Robotic transtibial prostheses which can intelligently adjust ankle angle are gaining popularity. In this paper, based on the light-weight robotic transtibial prosthesis with damping control, we further study the improvement on amputee's walking performance at different speeds on level-ground. Experiments on one transtibial amputee subject indicate that, compared with the passive prosthesis, the proposed robotic transtibial prosthesis has a larger range of ankle movement, which is closer to that of the able-bodied, and can improve amputee's gait symmetry and walking stability at different speeds.
